You're in denial of thousands of rigorous agronomy studies, over more than a century, which have measured the very large benefits of rising CO2 levels for agriculture. Of course, despite the benefits of elevated CO2, it's still possible to destroy agricultural productivity with bad governance. https://twitter-thread.com/t/1719372491536085167 Mao demonstrated that 60+ years ago, in pursuit of socialist utopia. Gotabaya Rajapaksa proved it again in Sri Lanka in 2021. Sri Lanka's humanitarian and economic disaster is the poison fruit of climate alarmism. Leftist politicians and climate activists are doing their best to lower crop yields, and return us to the days of mass famines. Most young people don't know much history, so they don't know what that's like. They're in for a very rude awakening, if the climate activists get their way. Compare: โ Covid-19 has killed about 0.1% of world population, so far โ The 1918 flu killed โ2% โ WWII killed โ2.7% โ But the global drought & famine of 1876-78 killed an estimated 3.7% of world population Dutch farmers are some of the most productive in the world, but their leftist, climate-conscious government is doing their best to end that: https://reuters.com/business/environment/dutch-farmers-protest-plan-curb-nitrogen-pollution-2022-06-22/ So is Baby Trudeau's leftist, climate-conscious government in Canada: https://agweb.com/news/policy/politics/new-policy-forces-canadian-producers-cut-back-fertilizer The Left and the Climate Industry are at war against agriculture, and against against humanity https://sealevel.info/learnmore.html?0=famine#famine In fact, the Climate Industry is ultimately at war against science itself. The IPCC's 2022 AR6 Report explicitly promotes homeopathic climatology (TCRE/RCB), which is just as unscientific as it sounds. Eli Rabett @EthonRaptor won't answer the question; so how about you, Willard? Do you agree with AR6 that CO2 which was FORMERLY in the air STILL has a warming effect? Or do you reject the IPCC's unscientific homeopathic climatology? Climate activists are like modern Lysenkoists, pretending to be scientific, while shredding real science. Or are you going to pretend there's anything scientific about GISS "climate scientist" @DrKateMarvel Kate Marvel's "intersectional science"? https://sealevel.info/intersectional_blah_blah_blah.html

1/7. The only trace on that graph which does not show large improvement in cereal yield per hectare is the trace for Niger. The graph ended with an anomalously bad crop year for cereals in Niger (2021). Fortunately, 2022 was much better; here's an article https://www.worldbank.org/en/news/press-release/2023/06/19/niger-strong-agricultural-season-boosts-economic-rebound-in-2022

2/7. By displaying high productivity countries like the USA along with Niger, you forced OurWorldInData to scale the graphs so that it's hard to see the trend in Niger. But if you display Niger alone, as I've done here, you'll see that cereal yields declined there until about thirty years ago, but they've improved since then (except for 2021).

4/7. That's probably because cassava benefits tremendously from additional CO2, especially in the dry conditions which are prevalent in most of Niger. Here's a paper about it: https://www.tandfonline.com/doi/abs/10.1080/03650340.2018.1446523 Cruz et al 2018. Elevated CO2 reduces whole transpiration and substantially improves root production of cassava grown under water deficit.

5/7. Most of Niger is desert or near-desert, which means most of its land is poorly suited for growing crops. Over the 60 year period shown, Niger's population increased by about 640%. As a result, the amount of land under cultivation drastically increased, resulting in more marginal land being put to the plow. That, of course, can be expected to lower the average cereal yield per hectare. Nevertheless, other than a bad year in 2021, yields there have been improving since the mid 1990s. https://sealevel.info/Niger_Cereal_production_1961-2021_OourWorldInData.png

6/7. That's probably because of the well-known fact that, in addition to improving production by CO2 fertilization, rising CO2 levels improve crops' water use efficiency and drought resilience. Here's a paper about wheat: https://onlinelibrary.wiley.com/doi/full/10.1111/gcb.13263 Fitzgerald GJ, et al. (2016) Elevated atmospheric [CO2] can dramatically increase wheat yields in semi-arid environments and buffer against heat waves. Glob Chang Biol. 22(6):2269-84. doi:10.1111/gcb.13263.

The science has been settled for over a century: elevated CO2 is tremendously beneficial for agriculture. The climate activists who refuse to acknowledge that established fact are science deniers. https://sealevel.info/learnmore.html?0=preciousairfertilizer#agriculture

I'm glad you finally understand that, according to NOAA's AGGI chart, over the last 1/3 century CH4 has accounted for just 8.6% of the radiative forcing increase from anthropogenic GHGs. I'm a bit worried about your failing memory, though. They say the mind is the second thing to go. https://sealevel.info/aggi_percentage_forcing_attribution_per_GHG_2022_annot1.png
@Willard1951 - James William Owens
@ncdave4life @ProfMarkMaslin @COP28_UAE I noted 6 days ago that the annual radiative forcing of methane was ~18% based on a quick look at the NOAA AGGI chart, Dave After showing you the AMS SoC tables, you now agree Yet, you still flounder and try to cover up your mistakes Why Dave?
@Willard1951 - James William Owens
@ncdave4life @ProfMarkMaslin @COP28_UAE Yes, the AMS SoC 2022 table was somewhat simpler with fewer minor GHGs With radiative forcing for 2022 in column #6 CO2 again row 1 = 2.3 W/m^2 CH4 row 2 = 0.56 W/m^2 About the same 4:1 ratio, as I've noted again & again
@Daniel_Marbella - Daniel
@Willard1951 @ncdave4life @ProfMarkMaslin James, if you read carefully, he claims about last 1/3 century, not since pre industrial times. After 1992 CH4 slope curves, adding just around 0,2 W/m^2 of radiative forcing in 30 years (0,0066 W/m^2/year). In fact, the effect of CH4 is truly magnified.
@Willard1951 - James William Owens
@Daniel_Marbella @ncdave4life @ProfMarkMaslin Dave is floundering, Dan Methane constitutes a significant human GHG emission and thus a significant contributor to the current warming of Earth's climate system
@Daniel_Marbella - Daniel
@Willard1951 @ncdave4life @ProfMarkMaslin According to modern evidence, CH4 only contributed about 0,6 W/m^2 since it was half nowaday concentration. And barely 0,7W/m^2 when doubled. The big factor as GHG is CO2.
@Willard1951 - James William Owens
@Daniel_Marbella @ncdave4life @ProfMarkMaslin As we noted in the thread on current contributions to radiative forcing CO2 ~65% CH4 ~18% And remember, CH4 has resumed its rise
@ncdave4life - โ๏ธ ๐บ๐ธ ๐บ๐ฆ Dave Burton
1/4. We've been over this, Willard. According to NOAA's AGGI chart, over the last 1/3 century CH4 has accounted for just 8.6% of the radiative forcing increase from anthropogenic GHGs. Not 18% or 25%. That's about 1/10แตสฐ of the contribution which we get from the ongoing rise in CO2. If that tiny contribution to modest and benign warming worries you, perhaps counseling would help.

@Willard1951 @ProfMarkMaslin @COP28_UAE Willard wrote, "CH4 increase is now returned to the higher rate" False. CH4 is rising nowhere near the higher rate of the 1960s and 1970s. Why do make guesses like that, and assert them as facts, without bothering to do the arithmetic to check them? The arithmetic is prettyโฆ

2/4. Here's the CH4 graph: https://sealevel.info/CH4.html https://sealevel.info/CH4_2012-2022_10.55_ppbv_per_yr.png Despite the modest uptick in CH4 level over the last 15 years, the rate of rise in CH4's radiative forcing is still much slower than it was 50-60 years ago. In the 1960s and 1970s the CH4 level rose relatively fast, and consequently CH4 was a larger contributor to radiative forcing increase.

3/4. The relatively sharp rise in CH4 level in the 1960s & 1970s was insufficient to reverse the worrisome 1950s-70s cooling trend. Here's a clip from CBS TV, in which Walter Cronkite, The Most Trusted Man in Americaโข, reporting: https://www.youtube.com/watch?v=H4JX1S9YZBo Hubert Lamb (source for that CBS story) was the founding director of the UEA Climate Research Unit. Here's a 1974 CIA report, based on the best current science, about the worrisome cooling trend: climatemonitor.it/wp-content/uplโฆ Here's an excerpt, from the Summary: "The western world's leading climatologists have confirmed recent reports of a detrimental global climatic changeโฆ during 50 of the last 60 years the Earth has, on the average, enjoyed the best agricultural climate since the eleventh centuryโฆ The world is returning to the type of climate which has existed over the last 400 years. That is, the abnormal climate of agricultural-optimum is being replaced by a normal climate of the neo-boreal era. The climate change began in 1960โฆ" The grim climate to which we were thought to be returning was the Little Ice Age. "Boreal" means cold: boreal. adj. Relating to or characteristic of the climatic zone south of the Arctic, especially the cold temperate region dominated by taiga and forests of birch, poplar, and conifersโฆ โโโโโโ โโ The global cooling scare was one of the main reasons for the shiny new anti-air-pollution laws governing power plants, in the 1970s. The other main reason was "acid rain." (Note: Unlike "acidified" oceans, which are actually alkaline, acid rain really is acidic.)
@ncdave4life - โ๏ธ ๐บ๐ธ ๐บ๐ฆ Dave Burton
4/4. But, Willard, you said "current warming." The CH4 rise 50-60 years ago is irrelevant to that. 1. The main anthropogenic factors affecting it are CO2 & air pollution abatement. 2. The main natural factors are probably Hunga Tonga (1/2022) & El Niรฑo. https://t.co/LDKUWm76lJ
